WILLIAM ERNEST BERTRAM, 0E BROOKLYN, NEW YORK, ASSIGNOR T0 HERMAN BIDDER, on NEW YORK, N. Y.

MONOLINE COMPOSING-MACHINE.

Specification of Letters Patent.

Patented July 11, 1911.

To all whom it may concern:

Be it known that I, VVJLLIAM ERNEST Bnnrnxn, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Monoline Gomposing-Machines, of which the following is a specification.

My present invention relates to improve ments in monoline composing and line-casting machines of the type shown in U. S. Letters Patent, No. 506,198 granted to V. S. Scudder on October 3, 1893, and it has for its object primarily to provide a generally improved machine of the type above mentioned and also one which is capable of holding and operating with two or more fonts of matrices to the end that the machine may set up matter containing type of two or more styles or sizes without the necessity of interchanging magazines or disturbing other parts of the machine, the change from one font to the other being accon'iplished readily by the operator, and the matrix selecting and releasing mechanism for the different fonts being operable from a single or common keyboard.

Another object of the invention is to provide in a machine of this type a traveling composing box which is so mounted and controlled by the matrix selecting mechanism that the composing box will be positioned directly beneath each particular magazine channel from which the matrix is delivered, a further movement of the composing box serving to convey each matrix to the assembling point, the traveling composing box enabling the matrices to drop thereinto with a perpendicular fall and through a short distance the height of the machine being thereby diminished and, moreover, greater speed in the composing is obtainable. To increase the rapidity in the operation of the machine, I also provide improved means for assisting the delivery of the matrices from the magazine.

Another object of the present invention is to provide an improved distributing mechanism for returning the matrices and spacers to the magazine channels and space vshowing the mechanism box respectively, such mechanism being relatively simple in its construction and operating with certainty and rapidity.

A further object of the invention is to provide an improved construction for the matrix bars whereby the hooks for suspending all of the bars of a font will be of the same length and, moreover, the length of the hooks may be shortened, this feature enabling the dimensions of the machine to be reduced and also reducing the distance of travel of the matrix bars from the magazine channels to the composing box.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing :-Figure 1 is a perspective view of my improvements as applied to a monoline composing machme, certain elements, however, which form no part of the present invention being omitted; Fig. 2 represents a section though the right hand portion of the machine and in elevation as viewed from the right in Fig. 1; Fig. 3 is a view similar to- Fig. 2, the parts, however, being viewed from the left hand side of the machine as shown in Fig. 1; Fig. et is a top plan view of the parts shown in Fig. 1; Fig. 5 represents a section on the line 5-5 of Fig. 2 and showing the parts in normal position; Fig. 6 represents a section on the line 6-6 of Fig. 5 and looking in the direction of the arrows; Fig. 7 is a detail enlarged view of the composing box which is shown in plan, and the actuating and controlling bars which control the delivery of the matrices, the composing box in this view being shown in a position to receive the matrix bar; Fig. 8 is a view similar to Fig. 7 showing the composing box in position to transfer a matrix bar to the assembling bar; Fig. 9 is a perspective view of the composing box carriage and related parts as viewed from the rear; Fig. 10 represents a section on the line 10-l0 of Fig. 9, the composing box being shown in normal or retracted position; Fig. 11 is a front elevation of the parts shown in Fig. 9, the composing box being shown in normal retracted posltion; Fig. 12 is a collective view of the parts of the composing box, the )fll'fS being shown in perspective; Fig. 13 is a perspective view of the bars which are actuated by the keyboard to deliver the matrices from the magazine and to arrest the composing box in a position to receive the delivered matrices;

Similar parts are designated by the same reference characters in the several views.

The machine forming the present embodiment of my invention is adapted to handle multiple letter matrix bars which are similar to those disclosed in the patent aforesaid in that the bar 1 contains a series of characters 2 on one edge and a corresponding series of alining notches 3 on its opposite edge. The matrix bars, however, are materially different in this respect, that each bar has a hook at toward its upper edge, the hooks of all the matrices being of uniform length and located at the same distance from the. bottom of the matrix bar and, moreover, the top of each matrix bar is provided with one or more distinguishing lugs 5, these lugs being placed differently on the matrix bars whereby during the distribution following each casting operation, the matrices will be returned correctly to their respective chambers and channels in the magazine. In the present instance, the machine is adapted to hold and operate with two fonts of matrices and in such cases, the distinguishing lugs will have a different form or location on each matrix bar in order that the matrix bars will be all returned to their proper places in the magazine. Each space bar 6, as shown in Fig. 25, is provided with a hook 7 which is located at a different elevation with respect to the hooks on the matrix bars when the space is supported by the lug 8 which rests on the alining bar, and the purpose of this will be hereinafter described. In the accompanying drawing, 1 have shown a composing and casting machine of the monolinc type as disclosed in the prior patent aforesaid. It will be understood, however, that certain features of the invention may be used in connection with composing and casting machines of a different type and, moreover, certain features of the invention may be used separately of one another although it is preferable to combine them in substantially the manner shown. It will be understood, of course, that modifications and changes may be made in the detail construction and in the relative arrangement of certain elements of the machine in order that the invention may be applied to the best advantage according to the circumstances of each particular case.

In the present instance, the machine embodies a main frame 9 which SUPPOXLS the magazine 10, the keyboard, the composing box, assembling devices, the elevator and distributing mechanism and associated parts. The magazine in the present instance is provided with two sets of channels, those of one set being designated 11 and those of the other set being designated 12, there being for example seven channels to containmatrices for one font and the remaining seven channels being adapted to contain matrices for the second font, the channels for the two sets preferably alternating. Two sets of distributing chambers 13 and 14 are also pro vided, the distributing chambers 13 serving to return the matrices of one font to the channels 11, while the distributing chambers 1ireturn the matrices of the second font to the channels 12. Each distributing chamber contains a rail 15 which slants downwardly toward the respective channel of the magazine, and this rail is adapted to cooperate with the hook of the corresponding matrix bar. Each channel of the magazine is provided with a delivery gate or pawl 16 which controls the discharge of the matrices, each pawl having an upwardly extending follower arm 17, a depending lug 18 with which a controlling detent 19 cooperates, and a spring 20 cooperates with each magazine gate or pawl. and serves to retract it. when released by the detent 1.) whereby a matrix may be delivered from this particular channel of the magazine. One gate or pawl 16 and its corresponding detent 19 is provided for each 0 iannel of the magazine, there being consequently four teen of these pawls and detents in the present instance, the detents for the two fonts being arranged preferably in alternating relation. These detents may all be pivoted to operate independently on a common shaft 21 which is supported by a stationary bracket 22, and each detent is provided with a depending arm 23 which when drawn forwardly serves to retract the detent and release its corresponding magazine gate or pawl.

The magazine gates or pawls may be restored to normal closed and locked posit-ion by means of an oscillator 2 1 which in the present instance is pivoted in bearings 25 secured to the main frame 9 and carries at its upper end a set of pawls 26 which are adapted to cooperate with the rear sides of the lugs 18 on the respective gates. This oscillator is provided with a roller 27 and said roller is adapted to be engaged by a cam 28 on an intermittently revolving shaft 29, the oscillator thereby receiving a to-andfro movement which will serve to restore at each forward movement such magazine pawls as have been unlocked and retracted. This shaft 29 is supported in suitable bearings on the main frame of the machine and carries a pair of clutch members 30 and 31. The clutch member 30 is freely revoluble on the shaft 29 and may be driven continuously in any suitable manner such, for instance, as by a pulley 32 which receives power from a belt 33. The clutch member 31 is splined to the shaft 29 so that it may move axially thereon so as to engage and disengage the clutch member 30, and a spring 34; normally acts on the clutch member 31 to throw it into driving connection with the clutch member 30. The clutch member 31, however, is normally held out ofengagement with the clutch member 30 by means of a clutch controlling arm 35-l1aving an inclined shoulder 36 at its upper end which is adapt ed to engage a correspondingly shaped proj ection 37 on the clutch member 31. hen, however, the arm 35 is retracted, it will release the clutch member 31 and the latter will be shifted by its spring 3 1 into driving connection with the continuously revolving clutch member 30, motion being thereby transmitted to the shaft 29 and the latter in turn will operate the oscillator to reset the magazine gates or pawls. ll hen the shaft 29 has completed a revolution, the sloping shoulder 36 on the arm 35 will cooperate with the projection 37 on the clutch member 31 and the latter will be thereby retracted so as to disengage from the clutch member 30 and at the same time the motion of the shaft 29 will be arrested.

The clutch controlling arm 35 is actuated by a shaft 38 which is mounted in suitable bearings on the stationary frame 9 and carries a lever 39 the upper end of which is connected by a link 10 to a rod 41, the latter being suspended in rear of the magazine gates or pawls by means of a pair of links 412. The cross rod t1 is normally held in a position to be engaged by the magazine gates or pawls by a tension spring 13. ll/henever agate or pawl is released and moves rearwardly under the action of its sprin 20, its rear end will strike the cross rod 4-1 and will move the latter rearwardly, overcoming the action of the spring 43 and rotating the shaft 38 so as to disengage the clutch controlling arm 35 from the projection 37. As soon as the magazine gate or pawl is re stored by rotation of the cam shaft 29, the clutch controlling arm 35 will return to a position to disengage the clutch and hold it in such condition.

The detents for the magazine gates or pawls are released by a single set of actuating bars 441, there being seven used accord ing to the present invention, this single set of actuating bars being operative from the usual single or common keyboard, and they are shiftable in order that they may be set into position to release and deliver matrices of one or another font as may be desirable. These bars in the present instance are guided at their forward ends by a comb block 45 which is fixed to the main frame 9, and the rear ends of these bars are shiftable laterally a distance corresponding to the distance between two adjacent detents 19 whereby such bars may be set to actuate one or another set of the depending arms 23 of the detents. F or this purpose, the rear ends of the actuating bars are slidably fitted in a comb block 46, the latter being shiftable in a direction transverse to the length of the bars in a guide plate t7, the guide plate being fixed to the machine frame. Any suitable means may be provided for retaining the shiftable comb block 46 in one or another of its two positions in order that the bars 4. 1 may actuate the detents 19 belonging to one or another font of matrices. In the present instance, T provide a pin a8 which is adapt ed for insertion into one or another of a pair of apertures 49 and 50 formed in the shiftable block as and the guide plate 47, respectively. The actuating bars at are provided with notches 51 to cooperate with one or another set of the detent actuating arms 23, and the rear ends of these bars are provided with upturned projections 52 which are adapted to be engaged by a reciprocatory resetting bar 53 which is placed above the bars and receives a to-and-fro motion from an arm 54L. This arm 54L is connected to a rocking frame 55 which is pivoted on a shaft 56 supported in suit-able bearings on the stationary frame 9 and the rocking frame 55 is provided with a roller 57 which is adapted to cooperate with and receive motion from the cam 28 on the intermittently turning and clutchoperated shaft 29. The resetting bar 53 is normally held in forward position to permit the bars 44 to operate freely by a tension spring 59. The forward ends of the bars 44.- are provided with depending projections 60 for a purpose to be hereinafter described. Each bar 44L is also provided with a depending lug 61 adapted to cooperate with a corresponding bail rod 62, these bail rods being actuated from the keyboard in any suitable manner such, for instance, as that disclosed in the prior patent above mentioned. These actuating bars at perform three different functions. The initial part of the forward movement of each bar a l serves to trip or release a traveling carriage containing the composing box. A further movement of the bar carries its forward end into a position to arrest the movement of the carriage containing the composing box whereby the latter is automatically positioned directly beneath the channel from which the selected matrix has been delivered, and the final portion of the forward movement of the bar causes it to unlock the detent which corresponds to the gate for the channel of the magazine containing the selected matrix whereby the matrix is delivered from the magazine channel directly into the comp0s ing box.

The composing box in the present instance is mounted on and shiftable with a carriage 63 which is movable in the stationary front plate 64 of the machine. This carriage may be guided in any suitable manner to permit it to operate freely in substantial alinement with the assembling bar 65. In the present instance, the carriage is guided to operate in the front plate by grooves 66 at the top and bottom which cooperate with corresponding ribs 67 formed in the top and bottom of the opening in the front plate, and in order to insure a free movement of the carriage, I preferably provide a pair of rollers 68 which ride in a recess 69 formed in a part of the front plate, the shafts 70 of the rollers riding in slots 71 formed in the carriage. The forward side of the carriage is provided with a pair of lugs 72. A pin 78 is non-rotatab1y'fitted in such lugs and has a wing 74 loosely mounted thereon. This wing 74L forms the forward side of the composing box and it has a blade 75 attached thereto which serves to guide the matrix bar while entering the composing box and properly positions it therein. The lower end of the Pin 73 has a guard 76 nonturnably attached thereto, and this guard is adapted to cooperate with the forward edge of each matrix bar and prevent its fallin from the composing box while the wing 4: is opened to permit the transfer of the matrix bar from the composing box to the assembling bar. The wing 74: is automatically opened when the carriage reaches a position to transfer the matrix to the assembling bar. The means shown in the present instance for accomplishing such purpose consists of a slide 77 which is guided to operate in longitudinal grooves 78 formed in the carriage 63, and a compression spring 79 is interposed between the body portion of the carriage and the slide 77 and acts to normally hold the slide 77 in retracted position. This slide 77 carries a plate 80 which serves to close the right hand side of the composing box and it is inclined toward its upper end so as to guide the matrix bars while entering the composing box. This plate 80 is rigidly attached to a lug 81 formed on the slide 77. The slide 77 operates in the carriage behind the pivoted wing 7a of the composing box and between the stationary lugs 72, and it is provided wit-h a pair of opposed lugs 82 which receive between them a roller 83 carried by an arm 84, the latter being formed as a part of the wing 74. At the left hand or discharge side of the composing box is arranged a movable retaining wing 85 which is capable of being deflected out of the path of the matrix while the latter is being discharged from the composing box. This wing is fitted in an opening 86 in the carriage and is turnable about a shaft 87, a spring 88 serving to normally hold the wing 85 in a position to assist the blade 75 on the movable wing 7 4. The detents 89 serve to retain the assembling line of matrices on the bar 65, each matrix as it is delivered from the composing box deflecting these detents in order that they may receive the matrix so delivered. The slide 77 on the traveling carriage is attached to a link 90 by means of the pivot- 91, the other end of the link being attached to a bell-crank lever 92which lever in turn is connected to a reciprocating bar 93, the latter being suitably guided to reciprocate on the main frame 9 and is provided toward its rear end with an upturned arm 94 carrying an operating roller or projection 95. The clutch-driven shaft 29 is also provided with a cam 96 to operate upon the roller 95 and. thereby force the arm 94 forward. The bar 93, however, is normally held in retracted position by means of a compression spring 97 which may be interposed between the upturned arm 94 onthe bar and one of the guide blocks 98 which is fixed to the stationary frame. The link 90 which is operated by the bell-crank lever 92 is formed on its under side with a stop 99 which is adapted to engage the upper portion of the forward end of one of the bars 44 when such bar is moved forward, whereby the traveling carriage will be stopped in its travel at a. point to position the composing box directly beneath the magazine channel from which the selected matrix is delivered. In operating the machine to compose matrices of one font, this stop 99 is in use. "When, however, another font of matrices is being selected and delivered from the magazine, 1 provide a supplemental stop which will position the composing box precisely beneath the channels containing the matrices of the other font. This supplemental stop consists in. the present instance of a plunger 100 which operates immediately in front of the fixed stop 99 and it may be manually shifted into operative and inoperative posi tion by means of a "finger lever 101 which may be pivoted on a shaft 102 supported in suitable bearing lugs on the link 90. An expansion or friction spring 103 may be arranged between one of the bearing lugs and the finger lever 101 so as to frictionally retain the supplemental stop 100 either in op erative or inoperative position. The traveling carriage is also provided with a shoulder or stop 104 and this stop serves to retain the carriage normally in retracted or initial position. In the present instance, this shoulder or stop 104 cooperates with a pawl 105 forming part of a rocking frame 106, the latter being pivoted on a shaft 107 supported in suitable bearing lugs 108 on the stationary frame, and the lower part of the frame 106' carries a roller 109 which lies immediately in front of the depending projections 61 on the forward ends of the bars 44. The frame 106 is normally held in such a position that the pawl 105 will cooperate with the shoulder or stop 104 on the carriage and thereby retain the latter in retracted position by a spring 110. The forward movement of any one of the bars 44, however, will cause thesame to operate upon the roller 109 so as to tilt the frame 106 and thereby disengage the pawl 105 from the stop or shoulder 104, the carriage being thereby tripped or released and it will be shifted with the composing box toward the assembling line of matrices under the action of the spring 97 operating through the bar 93, bell-crank lever 92, link 90, slide 77 and spring 79. The forward movement of any one of the bars 44 also causes the upper portion of its forward end to engage either the stationary stop 99 or the adjustable supplemental stop 100 according to the font of matrices in use, the carriage being thereby arrested in its travel so as to position the composing box to correctly receive the selected matrix. As before stated, the final forward movement of each bar 44 opens the magazine gate 01' pawl so that the selected matrix may be delivered from the magazine. Vhen the magazine pawl is retracted, it sets the cam shaft 29 into operation, and the cam 58 will thereupon set the resetting bar 53 into operation, thereby retracting the particular bar 44 that has been shifted forward. When the bar 44 is thus restored, its forward end will be disengaged from the stop 99 or 100 as the case may be, and the spring 97 will then complete the forward movement of the carriage and the composing box, The carriage upon completing its forward movement strikes the forward wall 111 of the front plate 64, the movement of the body portion of the carriage being thereby arrested, but the slide 77 will continue in its movement, the spring 97 overcoming the spring 79, and the lugs 82 will operate upon the roller 83 in a manner to swing the wing 74 into open position. The continued forward movement of the plate 80 and the slide 77 serves to eject the matrix from the composing box and while the matrix is being so ejected, the wing 85 is deflected, it immediately returning, however, to normal position after the passage of the matrix under the action of its spring 88. The traveling carriage and the composing box thereon is immediately returned to normal retracted position after the discharge of the matrix bar through the link 90, bell-crank lever 92 and bar the roller 95 on the bar being operated by the cam 96 on the cam shaft 29.

From the foregoing description, it will be understood that the carriage can be adjusted so that the composing box will be positioned directly beneath the channels containing the matrices for one or another font merely by manual adjustment of the finger lever 101. It will be also understood that the spring 79 which is interposed between the body portion of the traveling carriage and the slide 77 normally serves to retain the wing 74 of the composing box in closed position with the ejecting plate 80 retracted so as to permit the matrix to drop freely into the box.

The present invention also provides simple and improved devices for assisting the discharge of the selected matrices from the respective channels of the magazine. These devices each embody a bar 112 having a slotted blade 113 which is adapted to operate in a guiding slot 114 formed in the upper portion of the housing 115 of the magazine. For convenience, the guiding blades 113 of all of these devices are arranged in alinement, and rods 116 may extend through the housing and operate in the slots of the guiding blades 113. A spring 117 is also provided for each matrix discharging bar, its upper end being preferably seated in the housing of the magazine while its lower end rests upon a seat 118. Each matrix delivery device also embodies a plunger 119 which normally rests upon the top of the foremost matrix in the respective magazine channel. All of the matrix discharging devices may be reset from a common device which in turn may be actuated from the cam shaft 29. The resetting device shown in the present instance consists of a rock shaft 120 which may be suitably journaled in the magazine housing and is provided with a pair of crank arms 121 which carry a cross arm 122, and this cross arm may also be fitted with a roller 123. The roller 123 extends across the several channels of the magazine and is adapted to bear against an abutment surface 124" on each matrix discharging device when the shaft 120 is rotated in one direction. Normally, however, the roller 123 will occupy a depressed position as shown in full lines in Fig. 16, it being then clear of the abutment surfaces 124 of the several matrix discharging devices so that any one of them may descend under the action of its spring and accelerate the discharging movement of the foremost matrix. The shaft 120 may be conveniently operated by a crank 124, this crank in turn being connected to a link 125 and the lower end of the link is connected to one arm of a bell-crank lever 126, the other arm of the bell-crank lever being connected by a link 127 to a rocking frame 128. This frame 128 is pivoted on a shaft 129 supported by suitable bearing lugs on the main frame 9 of the machine and it carries on its upper end an operating roller 130. This roller 130 is arranged to cooperate with a cam 131 carried by the cam shaft 29 and it is held in engagement with such roller by a spring 132 which may be conveniently attached to the crank arm 124. All of the matrix discharging devices are normally resting upon the tops of the foremost matrices in the respective magazine channels so that when the magazine gate or pawl for any one of these channels is retracted, the matrix delivery device will i111- mediately operate under the action of its spring 117, the matrix being thereby discharged from the respective channel of the magazine with certainty and with an accelerating movement. Each matrix discharging device after so operating is automatically reset so as to be in a position to engage the top of the next matrix bar by the cam shaft 29 acting through the cam 131. After the matrices have been assembled and alined and the cast has been made, they are returned together with the spacers to the respective channels of the magazine and to the space box.

The present invention provides a simple and improved mechanism for elevating the matrices and spacers and for properly distributing them. In the present instance, a standard 133 is mounted rigidly on the stationary machine frame and is provided on its opposite sides with a pair of straight perpendicular guide grooves 134 and also with a pair of guide grooves 135 each of which has an offset or inclined portion 136.

The elevator according to the present invention operates vertically on the standard 133 and it is composed of two sections. One section 137 is yoke-shaped so to fit the front and two sides of the standard 133, and it has a pair of opposed ribs 138 which operate in the rectilinear guiding grooves 134 in the standard and it has a lug 139 within it which is pivotally connected to a link 140 which link in turn is connected to an operating lever 141. This operating lever is mounted on ashaft 142 supported in suitable bearing lugs on the under side of the main frame 9, and its rear end carries a roller or projection 143 which follows a cam groove 144 formed in a cam 145, the cam being fixed to and turnable with the cam shaft 146 mounted in appropriate bearings on the machine frame. The forward side of the elevator section 137 is provided with a rail 147 which is arranged at such an eleva tion as to receive the hooks 7 on the spacers as the latter are removed from the casting point together with the other matrices forming the line. The section 137 of the elevator also carries a relatively shiftable elevator section 148, the opposite sides of the section 137 being provided with grooves 149 to receive and guide the sides of the section 148, and the front of the section 148 is provided with a rail 150 which when the elevator is in lowered position is located at a proper distance beneath the rail 147 of the section 137 and is adapted to receive the hooks 4 of the matrix bars. The elevator is lifted from the shaft 146 and during the ascending movement, the elevator section 148 which carries the matrix bars is shifted relatively to the section 137 so as to carry the matrices out of the path of the spacers in order that the spacers and matrices may be distributed respectively to the space box and to the magazine. This relative shiftingmovement between the sections 137 and 148 is effected by a pair of rollers 151 which are attached to the sides of the elevator section 148 and
